i have a 2012 seeg that has been tuned with a fuelmoto head pipe and the fullsac 2" cores with no packing material and i like the way it sounds for the most part. if anything i would like it to have a little deeper tone but not any quieter. i have been reading here that adding the sleeves and some of the baffle material back would give me a little more torque, but what would it do to my sound? anyone tried it both ways? what was the sound difference?

hdff, Happy Labor Day Weekend to all! Regarding your question I think if you put in the packing   your sound will be more mellow and a little deeper, and maybe a little quieter. However on my own bike which has the fulsac 1.75 with the stock packing I have noticed that after 11k miles my bike is starting to sound a little louder, but still a very mellow sound for touring. I believe this is because some of the fiberglass packing is wearing away. I am not quite sure what you mean by screens unless you are referring to the metal mesh that holds the packing around the baffle. Let us know what you do and how it works out. CAHDBIKER

my bad i guess i got the name wrong, fullsac refers to them as sleeves not screens  http://fullsac.com/cvo-muffler-cores.html    they allow you to put half of the packing material back in. thanks for your reply

I originally installed the 2" Fullsac cores without any packing, because I knew what would happen to the packing if I just installed it over the cores (it ends up all bunched up at one end).

The sound was very hollow....almost tinny.  Sounded better than stock, but still left something to be desired.

I bought the screens/sleeves from Fullsac once they were announced, expecting very little change in sound, but I was pleasantly surprised.  adding the packing back in with the sleeves to hold it properly against the outer wall of the mufflers got rid of the tinny sound completely.  Volume doesn't seem to have been reduced by much, if at all, and it has a much deeper tone to it now.  One purchase I was very pleased with.

exactly what I was hoping to hear...  thanks

I installed the Fullsac 2" with the expanded metal screens (aka, CVO Perforated Muffler Sleeves) two weekends back. Intially I followed the Fullsac recommendation on using only 1/2 of the sound batting blankets in each can and the sound was deep and throaty as I'd expected it to be.  However, after a two hour ride to the mountains my ears were ringing from the exhuast din and I ended up putting in my my ear plugs.

On a hunch, I pulled the cores and sleeves and added back the other 1/2 of the sound batting to each can which is easy to do with the slip-ons still installed on the bike: just move the heat shields so you can remove the three screws holding in the exhaust tip, pull the tip, remove the Fullsac Core retaining screw and pull out the core with a twist of the wrist. The screens & sound batting come out just as easily.

I had to do a tight wrap of the sound batting around the screens so they'd fit back in, but other than that it was an easy re-install.  The cores slide right down the opening, albeit with only about a 1/4" of clearance all the way around. Popped on the end caps, tightened up the shields and as I expected, the sound coming out of the rear pipe was still deep and throaty, but there wasn't nearly as much sound coming through the walls of the can, at idle or while riding.

In fact, we just finished a 600 mile loop up through Tennessee over the Labor Day weekend and the sound was great with no ringing in the ears.

Bottom Line: I think you can "tune" the sound to meet anyone's expectations and it's quite easy to do once you've done the initial installation. I'm almost tempted to try the 2.25" cores with the full sound batting to see what sounds like.  Mind you, I'm not a fan of open pipes or overly loud exhaust, and the Fullsac system has really hit the sweet spot for our 110" motor: love that bass note!

Photo below: This was the cans with just the 1/2 sound blanket as originally installed.  I split only one of the blankets so on the re-install one was a full blanket and the other can got the two-halves.

so let me get this right, now you have all of the stock blanket back in each can behind the sleeves. the sleeve allows an air gap between the baffle and the sleeve/blanket

if your going to use packing you will need the screens...I have the 2.25SD cores and just took the packing out after riding with them for 1000 miles. This is what they looked like! half burnt away and pushed down the end of the muffler....lost some torque .....left the packing out and love the sound of the SD and have my performance back.

Yes, the full-size, stock blankets are back in the cans behind the screens and the 2" cores slipped right in without any binding or contact with the screens.  Now, as to what constitutes "All of the stock blanket", here's a photo of what came out / went back in from one of the cans, bearing in mind that the blankets were tightly wrapped around a very compressed screen. What the batting now lacks in volume due to its compressed state, it makes up for with density.

I would not have thought you could wrap it tight enough to get all that back in. Good job!

Put all my packing back in too. It was a tight fit but with an extra hand it made it easier to do. Had mine done at Doc's, he knew exactly what to do since he had done lots of bikes before, made an easy job even easier. Went with the DX pipes and 2" cores. Nice deep rumble at idle and cruise but an authoritative bark when you get on it.

I have the 2" cores and sleeves with about 1/2 the packing installed. I like the deep sound and quiets down nicely when cruising. I have a few thousand miles on this setup and I think it sounds great. Barks but not obnoxious.
